When a charged particle zips through the chamber, the vapour condenses into a trail of droplets showing the particle's path and, if the box is placed in a magnetic field, its electrical charge.

当一个带电粒子快速穿越云室时，水汽会凝结形成一串小液滴，这样便标识出了该粒子的路径；若将容器置于一个磁场中，还能知道粒子所带电荷的性质。

By altering the furnace pressure rapidly, baneful gases, such as oxygen and vapour, could be eliminated from the chamber. Therefore, cementite and nitriding processes are accelerated.

And when its aluminium coating is replaced with silver in a year or two's time (a huge vacuum-chamber housed at the telescope's base will be used to deposit metallic vapour on to the mirror's reflecting surface), it will be able to see into the infra-red with equal clarity, opening up a much neglected area of astronomy.
